May there be Peace in the Trees, May there be Peace in the Spiritual Beings in the various Worlds, May there be Peace in The Way,
May there be Peace in All, May there be Peace Indeed within Peace, Giving Me the Peace which Grows within Me,
Om, Peace, Peace, Peace.

Om, Mag daar vrede wees in die Hemel; Mag daar Vrede wees in die Heelal
Mag daar Vrede wees in die Aardsfeer; Mag daar Vrede wees in die Water;  Mag daar Vrede wees in die Bosryk;
Mag daar Vrede wees in die Bomeryk; Mag daar Vrede wees in die Geesteryk van die verskeie Werelde; Mag daar Vrede wees in die Weg;
Mag daar Vrede wees in die Alles; Mag daar Vrede terstond te midde Vrede, Vanwaar kom die Vrede wat binne my groei
Om, Vrede, Vrede, Vrede
